Definitions
- the present invention relates to a method and a device for the storage of natural casings as well as frozen natural casings »
- Meat products are filled in natural casings.
- the natural casings used for this purpose come in particular from pigs and sheep.
- the intestines are removed from the slaughtered animals and used for meat packaging or; Sausage casing prepared. This processing essentially includes cleaning.
- the natural casings are usually stored in brine for use for preservation. Depending on the concentration of the brine, the natural casings may last for several weeks.
- the brine draws water from the natural intestine, so that the intestine's lubricity is reduced.
- the natural casings are therefore soaked before they are filled in order to largely remove the brine and in particular to make the inside of the natural casing more slippery during the filling process.
- the concentration of the salt in the brine has to be increased
- the soaking process before filling the intestines is extended and the lubricity is also reduced. This increases the share of broken intestines in the filling process.
- the natural casings can only be stored / kept for approx. 4 days.
- the technical problem on which the invention is based is to create a method and a device in which or in which freezing of the natural casings is avoided.
- This problem is solved by a method for storing natural casings, in particular pork and sheep casings for meat and sausage packaging, the natural casings being drawn up on essentially rod-shaped carrier devices and then deep-frozen to at least -50 ° C.
- the intestines are preferably deep-frozen to at least -60 ° C, particularly preferably to at least -70 ° C.
- Providing individual natural casings on separate, essentially rod-shaped carrier devices prevents the casings from freezing together and thus damaging the casings when thawing.
- the carrier facilities preferably fastened to a frame, the distance between the carrier devices being selected such that the natural casings drawn onto the carrier devices do not touch. It is particularly preferred to releasably connect the carrier devices to the frame. It is thus possible to pull the natural casings, preferably mechanically, onto the essentially rod-shaped support devices and then to connect the individual support devices to the frame.
- the method according to the invention thus preferably has the additional step of releasably attaching the support devices equipped with natural casings to a frame. This also has the advantage that the natural casings can be removed from the frame together with the carrier device after freezing and can also be transported together with the carrier devices.
- the freezing process is preferably controlled in such a way that the natural casings are frozen very quickly to a temperature of at least -30.degree.
- the subsequent further cooling can take place more slowly.
- This can e.g. B. can be achieved by effective cooling systems. These are able to remove large amounts of heat in a relatively short time.
- Commercially available cooling systems from Linde AG, Germany, are particularly suitable for implementing the invention.
- the shock freezing and, if appropriate, the entire freezing process are preferably carried out under a nitrogen atmosphere or with the addition of nitrogen.
- the entire freezing process is preferably carried out in less than 15 minutes, in particular less than 10 minutes and particularly preferably in less than 7 minutes.
- the shock freezing of the natural casings according to the present invention ensures storage for months, essentially while maintaining the Properties of natural casings. Microbial contamination is reduced to a minimum.
- the method according to the invention also has a positive effect on the maintenance of the water content in the natural casing, which in turn has an effect on improved further processing in the meat products industry.
- With conventional preservation with salt the water is extracted from the intestine and makes further processing more complex.
- the process according to the invention maintains the lubricity of the natural intestine after storage and thawing.
- Another advantage is that clean handling and hygienic shipping is possible.
- the brine otherwise used for storage and preservation can leak during transport or handling of the natural casings, which, in addition to contamination in the bottling plants or transport vehicles, has the disadvantage that the natural casings dry out and can no longer be used.
- Thawing of the frozen intestines according to the invention can be done within about 10 minutes. take place, so that the natural casings within 10 min. are fillable.
- the natural casings are preferably thawed in warm water, which may be mixed with suitable additives. Since the frozen natural casings according to the invention can be thawed quickly without impairing the quality of the natural casings, fluctuations in demand can be compensated for quickly. Compared to conventional natural casings stored in brine, this has the advantage that the natural casings can be made available much faster for further processing. In the case of natural casings stored in brine, it is necessary to soak them the day before in order to largely remove the brine and in particular to make the inside of the natural casings slippery for the filling process.
- the method according to the invention also has the advantage that no brine is required and thus there is no need to dispose of brine.
- the method according to the invention is therefore more environmentally friendly.
- the processing preferably includes desalting the natural casings and soaking the natural casings, if necessary with the aid of plasticizers approved under food law.
- the invention further relates to a device for holding natural casings mounted on rod-shaped carrier devices.
- the natural casings are mechanically placed on rod-shaped support devices, such as plastic tubes, before freezing, so that the natural casing is present in a gathered form on the support device.
- the carrier device is then detachably attached to a movable frame together with the attached natural casing.
- the movable frame can then be placed in a refrigerator or freezer for freezing the natural casings.
- the device for holding natural casings that can be plugged onto rod-shaped carrier devices thus comprises a movable frame on which the carrier devices are detachably attached. It is preferably a plurality of carrier devices, so that a large amount of natural casing can be accommodated on a frame and frozen together.
- the device according to the invention makes it possible to economically freeze a large amount of natural casing in order to enable long-term storage and simplified further processing of the natural casings.
- the carrier devices are preferably held on the frame in such a way that touching the natural casings placed on the carrier devices is avoided during the freezing process. This avoids tearing or damaging the natural casings during further processing.
- the frame has receiving devices with at least one holding element.
- the holding element serves to hold the carrier devices, the Holding elements are designed such that the carrier devices can be connected to the holding element by means of a plug connection.
- the holding element is preferably rod-shaped lugs with an outer diameter which corresponds to the inner diameter of support devices in the form of tubes. This enables the carrier devices to be simply plugged onto the holding elements.
- the holding elements are preferably designed in such a way that the carrier devices are arranged rising from the holding elements. This has the advantage that the natural casings, when they are on the movable frame, cannot slide off the carrier devices. A separate protection of the natural casings against sliding down is therefore not necessary.
- the individual holding elements provided on the receiving device are arranged at a distance from one another which is dimensioned such that contact with the natural casings is avoided. This prevents damage to the natural casings during freezing and during subsequent processing.
- At least five, particularly preferably at least seven and in particular at least nine, holding elements are provided on the receiving device of the frame.
- the number of carrier devices provided on a receiving device is preferably selected such that an entire bundle of natural casings can be accommodated per receiving device.
- a bundle is a commercially available unit with a length of 91.4 m.
- the individual natural casings drawn onto the carrier devices inserted in a receiving device thus have a total length of 91.4 m.
- the receiving devices are also connected to the frame via plug-in elements.
- the receiving device equipped with carrier devices is then connected to the frame by the plug-in element.
- the plug-in elements are preferably sleeves into which the receiving elements can be inserted.
- the frame preferably has a plurality of receiving devices. The number of receiving devices is selected so that an increased loss of moisture in the natural casings is avoided during the loading of the frame.
- the natural intestine is preferably soaked in the form drawn on the carrier devices, if appropriate in the presence of plasticizers, and after soaking on transportable racks.
- the movable rack is pushed into a corresponding cooling or freezing system for deep-freezing.
- the natural casings are deep-frozen in this, preferably for 7-10 minutes at about -70 ° C. Freezing is preferably carried out under a nitrogen atmosphere or with the addition of nitrogen.
- the frozen natural casings drawn onto the tubes or carrier devices are removed from the freezer and packaged. Further storage and transport take place in the deep-frozen state, preferably at a temperature of -5 to -10 ° C.
- the user can use the natural casings in the store frozen state for several months without the natural casings losing their suitability as a sausage casing.
- the use of deep-frozen natural casings has the advantage that the process times in the further processing of the casings can be considerably reduced, since the natural casings can be thawed and further processed within a few minutes, in particular less than 10 minutes.
- This also has the advantage that even short-term fluctuations in demand can be quickly compensated for.
- natural casings inserted in Lake they have to be soaked the day before. If natural casings are only soaked for a short time, the brine is not sufficiently removed from the natural casing, so that the natural casing can burst more easily when it is filled. This increases the manufacturing costs and the consumption of natural casings and fillers such as meat or sausage.
- Another advantage is that the transport costs for frozen natural casings are considerably lower, since the natural casings do not have to be transported to Lake and the shipping weight is therefore significantly lower.
- the present invention also relates to a deep-frozen natural intestine, which is pulled onto a rod-shaped carrier device, in particular an essentially cylindrical carrier device.
- the frozen natural casing is obtainable by a shock freeze process according to the invention.
- the natural intestine according to the invention is preferably suitable for industrial processing, since there is efficient processing with little preparation effort.
- Pig casings for filling with sausages are desalted and soaked with an aqueous solution containing a plasticizer.
- the treated like this Guts are drawn up on tubes and at the same time floated from the inside with the aqueous solution.
- the drawn intestines are placed in the above solution.
- the tubes with the intestines should not touch each other and should be placed one after the other as quickly as possible in order to maintain the water content in the intestine. This is followed by driving the car into a blast freezer and frost defrosting to about -50 ° C to -80 ° C, preferably -65 ° C to -75 ° C, with the addition of nitrogen.
- the intestines can then be removed and bundled in order to obtain the standard commercial unit from a bundle, 91.4 m.
- the packaging takes place in boxes with insert bags, which preferably contain one, three or five bundles. Storage and shipping are frozen.
- Fig. 1 is a schematic side view of an embodiment of the invention
- Fig. 2 is a schematic front view of the embodiment shown in Fig. 1.
- the embodiment of the frame shown in FIGS. 1 and 2 has, on a base plate 12 provided with rollers 10, two supports 14 arranged one behind the other in FIG. 1.
- a plurality of plug elements 16, 18 are provided on each carrier 14.
- the plug elements 16 are each at a substantially constant distance from one another, arranged one above the other.
- a plug element 18 is provided opposite each other, so that mutually opposite plug element pairs 16, 18 are formed.
- a receiving device 20 is inserted into each plug element 16, 18.

- the holding elements 22 provided on the receiving devices 20 are oriented obliquely, so that the carrier devices 24 are arranged in an increasing manner, insofar as the receiving devices 20 are inserted into the plug elements 16, 18. This prevents the natural casings 26 from sliding down.
- the individual carrier devices 24 are equipped with natural casings with the aid of a machine, the natural casings then being present in a gathered form on the carrier devices 24. Subsequently, the carrier device equipped with natural intestine is pushed onto a holding element 22 by hand or automatically. It is not necessary here that the receiving device is already inserted in a plug element 16, 18 of the frame.
- the receiving device 20 can also be held in a holder provided next to the machine.
- the next carrier device is then fitted with natural intestine and again placed on the receiving device 20. If all of the holding elements 22 of the receiving device 20 are equipped with carrier devices 24, the entire receiving device 20 is fastened to the frame by being plugged into a plug connection 16, 18.
- the next receiving device 20 is then fitted with carrier devices 24 on which the natural intestine is present.
- a frame can be loaded by two or up to four people at the same time. This reduces the time the natural casings stay on the rack before freezing. As soon as a rack is completely filled with natural casings, the rack is placed in a cooling or Move freezer. This can be done by simply pushing if the frames are equipped with rollers 10. The rack can also be moved automatically.
